"We're not counting people or users. We're not claiming this is counting users and we never have We're counting downloads. We don't count updates but we count all downloads. If we were counding users, we'd have to put some kind of tracking tools in the browser and we're not going to do that. If we want usage, we can get that from large tracker sites like onestat, websidestory, or thecounter. This isn't users or usage, though, it's downloads.
